Campaign Finance Database

Updated: October 12, 2014

Welcome to Wisconsin’s premier searchable computer database of campaign contributors to candidates for state office in Wisconsin. Regularly updated with financial support from MapLight, this database includes records of contributions of $100 or more from individuals to candidates for the Wisconsin Legislature as well as governor, lieutenant governor, attorney general, state school superintendent and state Supreme Court justices.

The contributor records in this database generally date back to 1993, although in limited cases contributions dating as far back as 1989 are included. State law only requires donors who give more than $100 to disclose their occupation and employer. Please note that, in general, contributions returned by the candidates are excluded from search results.

You have two options when searching for individual contributors. Use the simple search below to search by contributor, employer, city or candidate or use the advanced search to search by more varied criteria.

Contributions from political action committees (PACs) can be found elsewhere on our website.

Recent Updates

Updated through July 28, 2014 for the two Democratic legislative campaign committees and all but one constitutional office and five legislative candidates in the fall election. Independent candidates are not required to file the pre-primary report covering activity through July 28.  Added November 3, 2014: Individual contributor data for David Bowen, Democratic candidate in the 10th Assemby District, is also missing from the searchable database. His original report showed no contributions between July 1 and July 28. An amendment filed after we collected his data for that period and which we only discovered while collecting the most recent campaign data, reported nearly $5,000 such contributions. Contributions of more than $100 from this period can be viewed here along with contributions from the complete election cycle. PAC contributions during that period can now be found in the PAC database.

 
Updated through June 30, 2014 for all Supreme Court Justices, the Superintendent of Public Instruction, the current Attorney General and State Treasurer, the two Republican legislative campaign committees, and all incumbent legislators not running for reelection this fall.

Returned contributions have been removed.
